ImGuiTextBuffer: Added append() function (unformatted).

Removed trailing spaces (#2038, #2299)

Added checks for "zero-as-null-pointer-constant" warnings for older Clang (#2299, followup to #2277)

Comments about DLL boundaries and using TLS variables for GImGui. (#2292)

Various tweaks and fixes as suggested by PVS Studio (thanks PVS Studio!)

FreeType: Minor tweaks previous commit (#2285)

Version 1.68 WIP

Fixed cursor issue caused by 6890e08b when calling BeginChild/EndChild multiple times to reappend into a same child window. (#2282)

Version 1.67

Added a bunch of diagnostic ignore to cope with Clang -Weverything being absurd. Also fixed two legit warnings. (#2277)

FAQ entry, moved ImTextureId, Gallery links.

ImVector: Made a struct. Using T/T* in the code instead of value_type/iterator. Renamed index_from_pointer() to index_from_ptr() (was not documented, added in 1.63, users not supposed to use ImVector, hopefully not a big deal).

Minot internal tweaks, comments

Internals: LowerBound: Use raw pointer typedefs, we never use iterator anywhere else in the codebase. ...

Demo: Typo.
C98 fix.

Added IMGUI_USE_STB_SPRINTF (undocumented) (#1038)

Tests: Reworking hook prototypes for imgui-test to be faster and multi-context friendly.

Fixed animated window titles from being updated when displayed in the CTRL+Tab list. + Adding overkill helpers for reusing buffers. (#787)

Renamed ImFont::GlyphRangesBuilder to ImFontGlyphRangesBuilder. Keep redirection typedef (will obsolete).

IO: Renamed InputCharacters[], marked internal as was always intended. AddInputCharacter() goes into a queue which can receive as many characters as needed during the frame. This is useful for automation to not have an upper limit on typing speed. Will later transition key/mouse to use the event queue later.

Nav: Fixed an keyboard issue where holding Activate/Space for longer than two frames on a button would unnecessary keep the focus on the parent window, which could steal it from newly appearing windows. (#787)

Added bindings in Readme. Added internal IMGUI_DEBUG_LOG() helper. Comments, missing breaking changes note relative to imgui_impl_xxxx changes, not really part of core but worth adding in the imgui.cpp breaking change section.

Added sanity check to debug parent/child ordering issues (they would generally manifest with an assert/crash in EndFrame bu tthis assert will catch some earlier).

Internals: Extracted code out of EndFrame() into UpdateMouseMovingWindowEndFrame()

Alternative fix for bug introduced in d845135 (#1651), fix CTRL+Tab and fallback tooltip.

Revert "Fixes crash/assert bug introduced in d845135 (#1651): would assert when showing the CTRL+Tab list and or fallback "...." tooltip." ...

This reverts commit 1b0e38d.

Fixes crash/assert bug introduced in d845135 (#1651): would assert when showing the CTRL+Tab list and or fallback "...." tooltip.

Happy new year! & comments

Comments: fixed missing line in the "how a simple rendering function may look like" section (#2258)

Error recovery: Extraneous/undesired calls to End() are now being caught by an assert in the End() function itself at the call site (instead of being reported in EndFrame). Past the assert, they don't lead to crashes any more. Missing calls to End(), pass the assert, should not lead to crashes any more, nor to the fallback/debug window appearing on screen. (#1651).

Tweaked asserts
